FoS Position - Our Comprehensive Essay on Climate Change Science. This is a graphically intensive essay on most aspects of climate change with links to supporting data. Compiled by Ken Gregory. The sun is the main driver of climate change. Water vapor and clouds reduce the initial warming effect of CO2 emissions.

The reports by the Nongovernmental International Panel on Climate Change (NIPCC) provides the scientific balance that is missing from the overly alarmists reports of the United Nations' Intergovernmental Panel on Climate Change (IPCC), which are highly selective in their review of climate science. The report "Physical Science" shows that the warming due to CO2 emission will be modest and cause no net harm to the global environment or to human well-being. Negative feedbacks in the climate system reduce the model derived temperature sensitivity to values an order of magnitude smaller. Earth's surface temperature are largely driven by variations in solar activity, which may have contributed as much as 66% of the observed 20th century warming. - The report "Biological Impacts" shows that higher CO2 levels and warming enhances crop yields and has resulted in the greening of the earth.

This editorial from Dr. Arthur Rorsch and Dr. Peter Ziegler introduces the Special Issue of Energy & Environment which challenges the Anthropogenic Global Warming hypothesis and the projections of the IPCC. The set papers show that climate models fail to replicate past climate variations and "the frequency of extreme weather
events has not increased during the last few decades." The authors write "the effect of variations in solar
activity has been seriously underestimated by the IPCC."

This review of climate science by three Dutch scientists compares the hypothesis that anthropogenic emissions of greenhouse gases is the main cause of recent climate change to the hypothesis that the sun is the main driver of climate change. The paper shows that water plays an important role in stabilizing the climate through evaporation and changing cloud cover. The paper lists numerous discrepancies between the AGW predictions and observations. Changing solar ultraviolet radiation, and the flow of charged particles have a significant effect on atmospheric circulation and clouds.

Dr. Peter Ziegler presents this comprehensive review of the mechanisms of climate change. Dr. Ziegler is a professional geologist and was a professor of Global Geology at the University of Basel, Switzerland. His key conclusions: Climate change during industrial times can be fully explained by natural processes. IPCC underestimates the effects of direct and indirect solar climate forcing but overestimates CO2 forcing by assuming unrealistic positive temperature feedbacks from water vapor and clouds. The IPCC consensus on anthropogenic CO2 emissions causing Global Warming cannot be reconciled with basic data and is therefore challenged.
